TCP/IP Calculator? Active directory sites and subnets

Here is what I would like to do. Given an IP address I want to look up in AD using s.ds.ad the defined subnets and figure out if the ip address would fit into any of the defined subnets in active directory sites and servicies. Is there an easy
way to to this? Or do I need to write a TCP/IP converter?

I have a question about Active Directory in .NETFor my project I need to fetch results from Active Directory search page by page, because later I would need to bind it to the pageable DataGrid.

I tried to use .NET library DirectoryServices for that, but paging provided by this library is transparent to the user and is used only to increase the efficiency of searching, when results are too big. I.e. I cannot tell the DirectorySearcher to give me first page, then the next or previous page, it returns me all resulting pages in one bundle.

However, what I need is to explicitely get page after page directly from the AD searcher and to be able to go at least one page forward or backward.

The solution with copying all results to the DataBase and then do the paging is not accepeted by the clent, since it is too inefficient. And since it's a Web app, I cannot keep results in memory either.

I found some hints about COM Interface, but I could not find good and detailed examples or explanations. I aslo found this line of code: DirectoryServices.Interop.IDirectorySearch.ExecuteSearch(), but I don't know which libraries should i add to be able to compile this code.

If somebody could help me out with that problem, any suggestion is welcome, 'cause this issue is eating me alive :)

When i try to List the users from Active directory, i get this exception.

Error while processing.System.Runtime.InteropServices.COMException (0x80072020): An operations error occurred at System.DirectoryServices.DirectoryEntry.Bind(Boolean throwIfFail) at System.DirectoryServices.DirectoryEntry.Bind() at System.DirectoryServices.DirectoryEntry.get_AdsObject() at System.DirectoryServices.DirectorySearcher.FindAll(Boolean findMoreThanOne) at System.DirectoryServices.DirectorySearcher.FindAll()

The code i used is :

DirectoryEntry de = new DirectoryEntry(_path);DirectorySearcher deSearch = new DirectorySearcher();

deSearch.SearchRoot =de;

deSearch.Filter = "(&(objectClass=user) (cn=" + UserName +"))";

SearchResultCollection results = deSearch.FindAll();

But the DirectoyEntry method is getting validated if i use the overloaded method : DirectoryEntry(_path, domainAndUsername, password);

This article explains how you can use Active Directory Federation Services (AD FS) 2.0 to claims-enable Windows Communication Foundation (WCF) services and browser-based applications. The focus is on the token issuance functionality in AD FS 2.0. You'll find out how to use AD FS 2.0 as an identity provider; set up an AD FS 2.0 security token service (STS) to interact with WCF; federate AD FS 2.0 with your custom STS or another AD FS 2.0; enable Web single sign-on and federation with WS-Federation and SAML 2.0 protocols; and externalize authentication logic through Visual Studio. You'll come away appreciating how AD FS 2.0 and Windows Identity Foundation make programming identity solutions in Windows less of a chore.

System.DirectoryServices is a managed code layer on top of Active Directory Service Interfaces, and you can employ it to better manage Active Directory from your code. Here Ethan Wilansky helps you get started.

Site user visits http://intranet/ , authenticates using intranet\username as username using proper password. Everything works fine.

Scenario 2:

Site user visits http://somedomain.com (that is forwarded to IP address of "intranet") , sharepoint opens, authenticates sometimes but sometimes it wont. Even if it authenticates user , some actions (edit an item) pops
up authentication dialog box and fails to authenticate further even with correct credentials.

Hello
I've got such openquery
SELECT * FROM Openquery(ADSI, 'SELECT EmployeeID, displayname, mailAddress,
country FROM '' LDAP://MY-LDAP-PATH ''
WHERE country=''coutry_code' ' ')
country_code is 3 letters i think sth in format like USA, FRA etc
I will need to retrieve users from up to 3 countries let say and i would like to create from this query above a stored procedure (or better a FUNCTION) where someone calling a function can specify from which country does he/she wants to terieve users
- when none country specified a function should retrieve users from all 3 let say.
I'm not very advanced in programming in T-SQL yet so my question is -> can the variable be specified inside Openquery ?
like for example
SELECT * FROM Openquery(ADSI, 'SELECT EmployeeID, displayname, mailAddress,
country FROM '' LDAP://MY-LDAP-PATH ''
WHERE country=''@country' ' ')
ACTIVE DIRECTORY HAS LIMITION OF RETRIEVING 1000 RECORDS AT ONCE - BUT NONE OF THESE COUNTRIES HAVE MORE THAN COUPLE HUNDREDS HOVWEVER summing them in one query this number of course
will exceed 1000 recoreds so queries i think should be splitted and joined with union ???
Can anyone provide some example code of such function
The other problem i have is that openquery againt ADSI above works correctly when i use SSMS localy on the server (connectin

Hi,
im new to sharepoint 2010. im in a situation whereby i would like to allow users that already have Active directory accounts log into sharepoint. The problem arises when i need to allow external users to log into the sharepoint site too and it will not be
possible to add them into the active directory. Is there a way to resolve this problem? Appreciate all help given! Thanks!

I've written a small ASP.NET 3.5 application to allow users to update selected account attributes on their own.
Everything works fine when I use Basic Authentication, but because the dialog that is presented is less than ideal, I'd like to use forms authentication to give the users more instruction on how to log in.
My problem is that in order for the user to update their account information, I have to have the application impersonate them for the update actions.
I've scoured the internet trying to find a solution to my issue, but nothing fits or works. I have tried setting the web.config:<identity impersonate="true" />
but that doesn't seem to work.
I also have the C# code using the WindowsImpersonationContext class, but still no luck. protected void titleTextBox_TextChanged(object sender, EventArgs e)
{
TextBox tb = (TextBox)sender;
string fieldTitle = "job title";
string fieldName = "title";
if (userDirectoryEntry == null)
CaptureUserIdentity();
try
{
WindowsImpersonationContext impersonationContext = userWindowsIdentity.Impersonate();
if (String.IsNullOrEmpty(tb.Text))
userDirectoryEntry.Properties[fieldName].Clear();

Hi there,I am just getting started with MVC and I was wondering if someone could point me in the right direction for help with forms authentication using active directory? I have the sample site up but the results I have found on google have not been very helpful in answering this question.This site is going to be an intranet page that we want users to be able to access without logging in when they access it from our network while they must login when trying to access it from home.Any suggestions of where to start?
